Cancer Therapies

8.5K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Tumor Immunotherapy

2.5K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Area of Science:

  • Biomedical Engineering
  • Oncology
  • Photochemistry

Background:

  • Photodynamic therapy (PDT) is a clinically established light-based treatment for various conditions, including cancer.
  • PDT involves administering a photosensitizer that accumulates in target tissues, followed by light activation.

Purpose of the Study:

  • To review current research and clinical outcomes of oncologic PDT.
  • To explore how basic science and clinical findings can refine future PDT applications.

Main Methods:

  • Systematic review of current PDT research and clinical data.
  • Analysis of photosensitizer accumulation, light activation, and resulting cellular events.
  • Evaluation of treatment outcomes, including tumor destruction and immune response.

Main Results:

  • PDT induces cell death via apoptosis and necrosis in tumors and neovasculature.
  • PDT can lead to immune system upregulation.
  • Cutaneous phototoxicity from sunlight is the most common side effect.

Conclusions:

  • PDT is a versatile therapeutic modality with a strong clinical record.
  • Ongoing research aims to optimize PDT efficacy and minimize side effects.
  • Future PDT applications may benefit from advancements in photosensitizer development and light delivery techniques.
